AVK BALL CHECK VALVE, FLANGED, TBL. D
NBR liner, EN558/48, SANS 664 coating, A2 bolts/zinc-coated A4 nuts
Ball check valve for treated waste water (not drinking water) and neutral liquids to max. 70°C. Max. operating pressure 10 bar
AVK ball check valves are full bore with a self-cleaning ball that rotates during operation rubbing off any impurity that could otherwise get stuck on the ball. The full and smooth bore ensures full flow with low pressure loss and low noise that keeps deposits from accumulating at the bottom. Valve bodies are available with flanges or internal threads and the balls come with NBR lining as standard or optionally with EPDM or polyurethane available in different weights from heavy to floating.| Variant 53/35-005 | |
